Functions as 5th degree scale of natural minor.
bVI
Flat Major 6th Chord

Functions as 6th degree of harmonic minor scale
V
Major 5th chord
Dominant

viio. Or viio6
Diminished 7 degree chord
Functions as 7th degree of major, harmonic and melodic scales . It can also be substituted for a dominant chord because most theorist consider it really a dominant function and not a chord in its own right.
Diminished chords are almost alway in first inversion so this chord would usually be seen as viio6, this is due composers disliking the tritone produce when in both root position and second inversion. The bass must be doubled.
viio or viio6
seventh degree chord
Leading tone
Functions as 7 degree in harmonic minor melodic minor and major scale.
Notice it is not flat because the seventh is raised in harmonic minor. In addition all diminished chords are in first inversion with a viio6 or viio6/3 in four part writing plus the bass or 3rd is usually doubled.
bIII
Flat major 3rd degree chord
Mediant
Functions as third degree of natural minor scale
bIII+
Flat augmented 3 chord
Functions as 3rd degree of both harmonic and melodic minor scales. This chord though is often avoided in baroque music due to voice leading. Also in harmonic minor when it is used it is substituted with a bIII major instead of augmented.
vi
Minor 6 chord
Submediant
Functions as the sixth degree of major scale.
Any chord tone in minor can be doubled however root is best doubled then after 5th. If a chord tone has to be omitted than the 5th is preferably omitted.
iio or iio6
Diminished 2 degree chord
Supertonic
Functions as second degree of harmonic minor and natural minor
Usually in first inversion and the 3rd or bass is doubled
ii
Minor 2 chord
Supertonic
Functions as the second degree of both major and melodic minor scale.
Supertonic chords are considered with the subdominant family
The fifth of this chord is the sixth degree and since in melodic minor the 6th degree is raised this chord changes from diminished ii from harmonic minor to minor ii from melodic minor due to fifth of the chord being raised.
vio
viØ7
Diminished six chord
This chord functions as the raised sixth degree of melodic minor. I say raised sixth because in harmonic or natural minor the sixth degree is b or flattened.
bVII
Flat major 7 chord
Functions as the seventh chord in natural minor
V6/4
Second inversion Dominant or fifth degree chord. Usually functions as a passing six-four chord where 1 chord in root position is followed by the V6/4 chord than followed by 16 chord in first inversion creating a passing tone in the bass between the “C” note in I and the “E” note in I6.
I6/4 or i6/4
This is called a cadential six four chord. This will precede the fifth degree chord of the scale and is usually considered part of the the dominant chord. This chord can also occur after a secondary dominant preceding the chord to be tonicized.
No chord tones in second inversion should be omitted and the bass must be doubled.
